Saier HW21WA Water Flow Sensor (1–30 L/min, 4.5–18V)
The Saier HW21WA is a turbine-based water flow sensor designed for precise flow rate monitoring from 1 to 30 L/min. Operating on a 4.5–18V DC supply, it provides both analog and digital output signals for easy integration with microcontrollers (Arduino, Raspberry Pi), PLCs, and IoT systems for liquid and gas flow measurement.
Features
- Turbine-based flow sensing with ±10% accuracy for reliable measurement.
- Wide operating voltage range of 4.5–18V DC for flexible system integration.
- Compact and durable housing designed for easy inline installation in confined spaces.
- Dual analog/digital output options for compatibility with various control systems.
- Suitable for monitoring both liquids and gases within specified pressure limits (≤1.75 MPa).

The Saier HW21WA Water Flow Sensor employs a precision turbine mechanism to translate fluid flow into a measurable electrical signal. As fluid passes through the sensor body, it spins an internal rotor, generating a pulse frequency or analog voltage proportional to the flow rate. This principle ensures consistent and repeatable measurements across its 1–30 L/min range.
Constructed with durable materials, the sensor is designed for long-term reliability in diverse environments. Its electrical interface is protected with high insulation resistance (>100 MΩ) and dielectric strength (AC500V, 50Hz), making it suitable for integration into industrial equipment, home automation systems, and IoT monitoring platforms where stable, low-current (≤15mA) operation is required.
